When logging in from a 7.6 Connector to a 7.6 VDI, the desktop disappears in view from the management console. Restarting the VDI will allow it to show up again in the console.
Connecting from a 7.5 connector doesn't produce the same issue.
Nothing happens to the actual VM record. The defect is that the console thinks it’s a header row and removes it from the display.
If you add the 'Connector Version' column in the management console view then the VDI's do not disappear.
